Description
Technical field
The present invention relates to the coating manufacturing technology in chemical industrial field, and in particular to a kind of heat reflection fluorochemical urethane face
Paint.
Background technology
Heat reflection anticorrosive paint, is to add a kind of functional paint that special type filler is configured to by macromolecule organic resin.It
The protection of existing general coating and decoration functions, again have reflected sunlight, barrier heat energy transmission characteristic, be collection anticorrosion and
The new special coating that heat insulation and heat control is integrated.
The effect of heat insulation of heat reflection anticorrosive paint, mainly by the particular fillers that are added in formula to the reflection of sunshine and
Obtain.Macromolecule organic resin is due to very high sun light transmittance, so the effect of film forming is only served in formula,
Heat reflection is not contributed, not only however, weatherability difference macromolecule resin heat reflection is not helped, can also reduce paint film
Insulative effectiveness.Out of doors in environment, Huang occurs under the irradiation of sunshine for the paint film using the macromolecule resin of weatherability difference
Change, efflorescence, making the L values of paint film reduces, further, since the efflorescence on surface causes paint film to be easier to be contaminated, pollutant accumulation
Coating surface is embedded in, low-L value is further dropped, and L values decline, the sun light reflectivity of paint film will decline, so that oily
The thermal insulation of paint is deteriorated.
In view of this, it is special to propose the present invention.
The content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art to have excellent weather resistance there is provided one kind, simultaneously
Also there is the heat reflection fluorochemical urethane finish paint for the features such as conventional polyurethanes coating gloss is high, bright-colored, adhesive force is good.
A kind of heat reflection fluorochemical urethane finish paint, is made up of two kinds of components of A and B, counts by weight, component A includes：
B component is isocyanate curing agent.
Trifluoro FEVE resins (CTFE type FEVE resins) Oil repellent is in 25% or so, the fluorine-containing unit of the fluorocarbon resin
It is made up of CTFE, Oil repellent is moderate, usual vehicle is dissolvable in water under normal temperature, the heavy antisepsis of proper formulation air drying is used
Coating.Preferably use the trifluoro FEVE resins of product 41165 of Taiwan Changxing Chemical Co., Ltd..Relative to other types of fluorine carbon
Resin, trifluoro FEVE resins have more preferable compatibility, therefore the gloss of film being made is higher, color is more bright-coloured, and matching is also more preferably.
Hydroxylated acrylic resin has high weather resisteant, and its special molecular structure causes there is very good with trifluoro FEVE resins
Intermiscibility, after trifluoro FEVE mixed with resin uses, can further lift the adhesive force and clarity of coating.Preferably use platform
The product 7331 of gulf Changxing Chemical Co., Ltd..
The color stuffing that dispersant is used in dispensing formulations, and produces tiny flocculation therewith, effectively prevent paint produce loose colour,
The disadvantage such as grow dim.Preferably use the product BYK-104P of BYK companies.
Titanium dioxide is harmless, and whiteness is high, strong covering power, and weatherability is excellent, and color stuffing is used as in inventive formulation
Add, to visible reflectance highest, its total amount is preferably controlled in the range of 22-24 parts by weight.
Heat reflection pigment is finish paint for the filler for reaching corresponding performance and adding, the present invention from using titanium dioxide as
Kernel, using rectorite, organic dispersion as the heat-reflecting heat-insulating material of parcel, has high reflecting effect to sunshine, is formulated
It is middle to add a small amount of pigment, so that it may to greatly improve the heat-proof quality of film.Preferably use the production of Shanghai Yutang Industrial Co., Ltd.
